physreg becomes ridiculously high.

std::upper_bound may be log(N), but for sufficiently large live intervals, it
becomes log(N)*cachemiss = a long long time.

This patch improves coalescer time by 4500x for a function with 20000
function calls. The generated code is different, but not significantly worse -
the allocator hints are almost as good as physreg coalescing anyway.

This patch updates LLVMDebugVersion to 8.
Debug info descriptors encoded using LLVMDebugVersion 7 is supported.

Corresponding llvmgcc and clang FE commits are required.
